Abstract: This study examined the roles of peer acceptance and friendship quality as moderators of the association between interparental conflict and internalizing symptoms in a longitudinal sample of elementary school children who were initially recruited in early childhood. Ratings of interparental conflict, peer acceptance and friendship quality were obtained from 103 parents and children at age seven (middle childhood), while child-reported internalizing symptoms were assessed at age 10 (pre-adolescence). Interparental conflict in middle childhood was not associated with internalizing symptoms during preadolescence for boys. However, girls who were highly accepted by peers in middle childhood were less likely to experience internalizing symptoms in pre-adolescence. Results suggested that the relationship between conflict and internalizing symptoms was attenuated for girls with high levels of peer acceptance. Additionally, girls who were both highly accepted by peers and had high quality friendships experienced the lowest levels of internalizing symptoms. Discussion of results highlights the importance of examining peer relations as a way to attenuate internalizing problems for girls.
